This study is aimed to improve the treatment, early diagnosis, prevention and prediction in propgnosis of oral and maxillofacial malignant tumors. The authors investigated about clinincal and histopathologic findings, treatments in 52 cases and
survival
rate of 23 cases to have been diagnosed and treated in the Department of Oral and Maxillofacial Surgery, College or Dentistry, Pusan National University from the 1st of January, 1986 to the 31th of September, 1993.
@ES The results were as follows:
1. Oral and maxillofacial malignant tumors occurred the most between 60~69 years of age and more often in males than females with a ratio 2.5 : 1.71% of patients were visited 3 months after onset of initial symptom and the tumors occurred the
most
in
Stage Ⅳ with 51.9% as 27cases.
2. Surgical therapy was used the most as single therapy.
Combined therapy for malignant tumor was executed more than single therapy in Stage Ⅲ, Ⅳ advanced tumor. Surgical and radiation was combined most frequently.
3. Regional neck dissection was operated most frequently for cervical neck nodes.
4. Overall 5 year survival rate of the patients possible to be investigated was 26% and overall 3 year survival rate was 43.5%.
5. The authors considered that higher stage of tumor, existence of combined disease, male than female coued be predicted poor prognosis but not in cell differentiation and age.
